Of course, everything that happened above had little to do with the dialect at this time, and he was hurrying down the sparsely sparse street towards the city's largest library.

But when he stood in front of the library, he could only shake his head helplessly when he looked at the closed door.

Although unexpected, it is reasonable......

200 years later, there is no data interface like in 2017, almost all data is stored and backed up by the cloud disk storage of the network, and some of the best things are based on the hard disk device of wireless transmission, and data transmission is carried out through specific encryption protocols and drivers.

It's embarrassing, but Fang Yan has long thought of this problem, it's useless to bring back a hard disk, isn't it over if you bring the computer back together?

The advance salary was 3,000 yuan, of which 1,700 yuan allowed him to buy the cheapest personal computer, then 400 yuan to buy a portable hard drive, and 500 yuan to buy all kinds of books before, but due to the high price of books, there were only 4 books on physics and mathematics, and the rest were downloaded online.

However, due to the complexity and messiness of the information and materials on the Internet, Fang Yan will want to come here to see, if there is a chance, it is better to buy a few regular books, if there is no opportunity, then it can only be like this.

"Little brother, try not to linger on the streets."

A voice came from the side, Fang Yan turned his head to look at the soldier, and then glanced at a few prepared positions not far away, then nodded and replied with a smile, "Okay, I'll go back immediately." ”

With that, Fang Yan quickly turned around and ran towards his residence.

At this time, the sound of various aircraft piercing the sky was constantly flashing in the sky, and a faint corner of steel peeked out of the clouds and slowly disappeared......

……

"It is impossible for the energy defense shield to have no upper limit of defense, Dongsheng, quickly gather all the forces of the defense circle to carry out a saturation strike on a battleship from beginning to end." Ma Donghai shouted at Dongsheng, the commander of Saturn's front finger.

"Understood!" Dong Sheng replied, then quickly turned around and looked at the starry sky battle map in front of him, and immediately said after pondering the 11 battleships on the opposite side in detail, "The entire fleet has it, and the alien right ship will be attacked with saturation coverage for 2 minutes, and the Xuanwu defense system will be activated at the same time to prevent the enemy from attacking!" ”

"The energy detection instrument is capturing the opponent's position, and the current distance is 197,000 km, which is within the range of the extreme strike, and the expected hit rate is 0.5%!"

"The location has been determined, the orbital laser cannon is being recharged, the nuclear electromagnetic cannon has been launched, the deep space nuclear bomb has been launched, the fleet is carrying out a saturation strike ......"

"The laser cannon hits 2, and the enemy has no reaction!" The staff next to him said quickly.

"Whew!" Dong Sheng exhaled, and then spoke again, "Totally, I need your analysis results!" ”

"The opponent's fleet consists of 2 supply ships, 1 multi-purpose ship, as well as 2 warships and 5 colonial ships, and the opponent's lead ship is estimated to be a special warship."

"Is there any tactical guidance?"

"Temptation with all your might!" Ma Donghai's voice came out, Dongsheng listened, and then slowly exhaled out,

"The Third Fleet, start the main engine, launch an attack on the enemy fleet from the left flank, and the rest of the fleet continues to defend, the main combat target, to test all the enemy's means of attack, the performance of the enemy's warships!"

"Understood!"

A deep but solid voice came from the side, Dong Sheng nodded, and then continued, "The orbital defense facility immediately covers the Third Fleet. ”

A faint blue light erupted from the tail of each battleship of the Third Fleet, and the 12 battleships quickly broke away from the original zigzag defensive formation, and then quickly rushed to the side, to be a tentative attacker, or cannon fodder......

Dong Sheng knew, but he still didn't hesitate, because someone had to take the first step to find out the sinister on this road for the followers, to test the real situation of the alien fleet, and to test their combat effectiveness.

The solar system is too big, and there are still too few humans, so they can't defend the solar system like an iron bucket, but they can defend the only Earth, that is, the Earth-Moon defense system is the final battle.

"The opponent's lead ship and two battleships are accelerating! 1000km/s, 2000, 3000 ......" The staff officer next to him shouted urgently, and on the screen, a small shuttle-type battleship was rapidly attacking the Third Fleet.

"All of them, choose their respective targets and strike immediately!" Dong Sheng yelled.

Before the words of the staff officer of "The Third Fleet and the Enemy ......" could be spoken, a fierce fire burst out from the place of the Third Fleet, and then it was directly cut off by the waist, and a little dark silver light flashed quickly, and then quickly disappeared.

"Disperse, the defending fleet immediately disperses, and the laser railgun carries out a covering attack on the enemy's lead ship! The rest of the ships were able to strike at the other two enemy ships. Dong Sheng shouted loudly.

"073 ship, 075 ship lost contact, 079 ship ......"

"The target is being tracked, and the trajectory of the target cannot be calculated!"

"The enemy shock ship does not have an energy shield, but due to the material, it adopts the most primitive ramming attack, and due to the speed, we have no way to attack and resist!" The analyst next to him yelled.

"Just fight us, his goal is to destroy our fleet, so he will concentrate on our area!" A calm voice came out of the communication, Dong Sheng listened for a moment, then took a breath and asked, "What is the current situation of the enemy?" ”

"The enemy has only dispatched 3 ships, and the rest have not moved at all."

There is no sound, only dead silence, and the war in space may be regarded as a silent war, with a flash of fire in the sky, and then under the microcosm of deep space, it seems unusually small.

"Ship 074 destroyed, ship 016 destroyed, ship 025 incapacitated......" voices rang out in Saturn's space station.

"All members of the defense, saturation strikes in the direction of the Third Fleet!" Dong Sheng said, and then looked at the battlefield on the image, the two enemy ships that were free from the main battlefield said again, "Abandon the other two enemy warships, turn their guns, Third Fleet, are you ready?" ”

"We're ready!"

"The First Fleet has been adjusted!"

"The Fifth Fleet has been adjusted!"

"The orbital defense facilities are all ready!"

Above the orbital defense circle, the guns of the battleships quickly turned their direction, ignoring the flash of fire around them, and the dark blue energy artillery that continued to attack in the distance......

"Fire!" Dongsheng watched a flash of light and silently spit out these two words.

There was no smoke, no sound, only a flash of light for a moment, only the sparks from the friction of the cannonballs when they came into contact with the steel, and the fire in the direction of the Third Fleet seemed to want to burn the entire starry sky, mixed with the dazzling light of the nuclear burst, but also the indomitable laser beam.

"Third Fleet, all destroyed!"

"Roger!" Ma Donghai's deep voice came out of the communicator.

"Fifth Fleet, there are only 4 warships left!"

"First Fleet, there are currently 6 warships left!"

"All of them, strike freely, the analysts immediately scan the location of the enemy shock ship!" Dong Sheng exhaled and shouted, then changed his tone, "No matter what the result is, special mother, each of your warships will hit me at least one shot!" ”

"Enemy shock ships spotted!" The staff next to him shouted, "We are heading towards our defensive circle position, destroying our Xuanwu defense facilities, and the S1 area has been destroyed......"

"Image!" Dong Sheng shouted, and at the same time, the image of the enemy's shock ship appeared on the light screen in the middle, making everyone in the battle hall involuntarily smile.

Because of that little depression, mixed with a little pothole and some charred black......
